Title: Innovations by John Blake
Introduction
John Blake is a notable inventor based in Limerick, Ireland. He has made significant contributions to the field of electrical engineering, particularly in the development of current measurement circuits and temperature sensors. With a total of 7 patents to his name, Blake's work has had a considerable impact on the industry.
Latest Patents
One of Blake's latest inventions is a current measurement circuit. This invention is designed to connect across a sense resistor that carries a current of interest. It features a first pair of cross-coupled switches linked between the sense resistor and respective input capacitors. Additionally, a second pair of cross-coupled switches connects the input capacitors to the inputs of a differential amplifier. The feedback capacitors are connected between the amplifier's outputs and inputs. A control circuit operates the switches according to a specific switching cycle, allowing for the sensed voltage to be sampled and transferred to produce a differential output voltage proportional to the current of interest.
Another significant patent is the four current transistor temperature sensor. This sensor comprises a p-n junction, preferably the base-emitter junction of a bipolar transistor, driven by four different currents in a predetermined sequence. Each current induces a respective base-emitter voltage, which is measured to calculate the transistor's temperature. The arrangement of the driving currents allows for the elimination of temperature measurement errors, providing a more accurate reading.
